A method for preparing 5′-monodeuterated nucleosides with defined , starting from glucose, is described. The 5-oxopentose derivatives, derived from glucose, were treated with LiAlD4 in the presence of LiI and/or t-amylalcohol to give stereoselectively 5-monodeuterated pentose derivatives. Using various reaction conditions, the stereoselectivity of the monodeuterated 5-hydroxymethyl group could be partially
